There have been six serious crashes causing injury or death since 2013, including one in which a man died after his car rolled down a bank and into a river.
NZ Transport Agency Waka Kotahi said the crash data included the period when the Covid-19 pandemic closed New Zealand’s borders, reducing traffic on the road.
About 40% of these crashes happened between 2016 and 2018.
In 2021, the road’s speed limit was reduced to 80kmh — from a mixture of 100kmh and 80kmh limits — after a public consultation showed broad support for the lower limit.
Since 2013, there have been seven deaths and 49 serious injuries on other sections of SH94, the Milford Road, which stretches 119km between Te Anau and Milford Sound.
Eighteen crashes were due to losing control on a bend and six were head-on collisions.
